NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 613,630, dated November 1, 1898.

Application filed January 20,1898- Serial No. 667,216. (No model.)

To all whom it may concern:

Be it known that I, JUDSON IV. I-IInEs, a citizen of the United States, residing at Elma, in the county of Chehalis and State of Washington, have invented certain new and useful Improvements in Nut-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in nut-locks; and the object thereof is to provide a simple, cheap, and effective construction of nut-lock for locking the nut upon the bolt and preventing the accidental displacement thereof.

lVith the above obj ectin View the invention consists of the novel details of construction hereinafter f n11 y set forth in the specification, particularly pointed out in the claim, and clearly illustrated by the accompanying drawings, in which Figure l is a front elevation of a nut and bolt having my improved nut-lock applied thereto. Fig. 2 is a longitudinal sectional View of the same. Fig. 3 is a plan view of the washer constituting the nut-lock. Fig. i is a vertical longitudinal sectionalview showing the nut-lock positioned between two nuts and locking the same upon the bolt. Fig. 5 is a similar View showing the construction of the locking-washer when the object against which it bears is of wood. Fig. 6 is a plan view of the same construction of washer.

Fig.7 is a plan view of a modified form of washer. Fig. 8 is an edge view of the same.

Fig. 9 is a vertical sectional View showing a further modification.

Referring to the drawings, A indicates a bolt, and O a nut engaging the same. The locking-washer D is slit inwardly radially, forming a plurality of locking portions or tongues The slits do not extend entirely to the central opening F, but terminate short thereof, as illustrated in Fig. Tongues G extend into said bolt-opening F of the washer on opposite sides of its center'and are bent forwardly, as illustrated in Fig. 2, to extend into enlargements formed at opposite sides of the bolt-opening of the object against which the nut boa-rs. Should this object be afishplate, these enlargements will not have to be formed therein inasmuch as the bolt-opening therein is usually oblong, so that a space or enlargement is provided at each side of the bolt. These tongues prevent the rotation of the washer, and a very simple yet effective construction is provided. After the nut has been properly adjusted one of the lockingtongues of the washer is bent to engage the nut, so that the latter is locked from rotation. By having the tongues formed about the en tire surface of the washer by slitting the same radially a locking-tongue is always in position to engage the nut regardless of the position assumed by the latter when it has been properly adjusted upon thebolt.

When the locking-washer is positioned between two nuts, as shown in Fig.4, one of the tongues E may be bent in one-direction to engage the nut H, while another may be bent in the opposite direction to engage the nut I. Thus the washer can be used to lock two nuts at the same time and prevent rotation thereof upon the bolt. In this construction the tongues G are not used, as they are not necessary, as will be understood.

Should the object against which the washer is to bear be of wood, as illustrated in Fig. 5, a somewhat different construction is provided. In this instance the channels or grooves in the bolt are dispensed with as also are the spring-tongues of the washer which engage said grooves. The washer in this construction has the oppositely-extending tangs K, formed on opposite sides of and adjacent to the bolt-opening by slitting said washer and springing the slit portions outwardly-at right angles thereto. These tangs engage the wood against which the washer bears and are forced thereinto by the nut, so as to prevent rotation of the washer. The locking construction of the washer, by means of which the nuts are prevented from rotating upon the bolt, is the same as that first described.

In the modification illustrated in Figs. 7 and 8 each tongue E of the washer is formed with a flute or corrugation L in its outer face, so that when the same is positioned upon the bolt and engages the fish-plate or other object against which it is adapted to bear a round or pointed tool may be inserted in the corrugations and the tongues readily bent to engage the nut.

In the modification illustrated in Fig. 9 the bolt is formed on opposite sides of its center with longitudinal grooves or channels 13, and when the washer is forced upon the bolt the tongues G bend backwardly to form springtongues, which extend into the bolt-opening of the nut. These tongues prevent rotation of the washer and by engaging the bolt tend to prevent backward movement of the washer thereon. By having the tongues extend into the bolt-opening of the nut they are securely held in engagement with the bolt. The washer may be made in any preferred shapeas, for instance, square or oblong.

From the above description it will be seen that I have produced a very simple construction of nut-lock which takes the place of the ordinary washerand which is exceeding cheap of production and very effective in operation, as has been demonstrated by actual tests.

Having thus fully described my invention,

what I claim as new and useful, and desire to secure by Letters Patent, is

In a nut-lock, the combination with a bolt and a nut, of a locking-washer consisting of a circular disk provided with a central opening to receive the bolt and slitted radially from a point adjacent to said opening to the outer edge thereof to form a continuous series of bendable tongues, either one of which is adapted to be bent over upon the nut, said tongues being provided with central longitudinal flutes or corrugations, formed by indenting the same, and a pair of tongues or looking projections arranged at opposite sides of said central opening, substantially as described. H

In testimony whereof I aflix my signature in presence of two witnesses.

JUDSON W. IIIMES.
